Abstract
A barrier package for an aerosol container may have a body with a pleated plastic side wall which is strengthened as a result of formation of the side wall by re-heating, stretching and blow molding a pre-form. In fabricating a barrier package into an aerosol container, the package with attached valve cup may be positioned in the mouth of a canister so as to leave the mouth open and propellant injected into the mouth. An aerosol container may have a barrier package with a self-supporting pleated plastic body.
Description
- The present application claims the benefit of prior provisional application Ser. No. 60/752,908, filed Dec. 23, 2005, the contents of which are hereby incorporated herein by reference.
- This invention relates to a barrier package and to an aerosol dispenser incorporating such a package.
- Aerosol dispensers are used to dispense a wide variety of products. For certain products it is desirable, or necessary, to isolate the product from the propellant. As described in U.S. Pat. No. 4,238,264 issued Dec. 9, 1980 to Pelton, one manner of achieving this is to introduce a laminated plastic film liner into a canister with a special tool that creates a vacuum inside the liner so that the liner collapses onto a central tube to have a diameter less than that of the canister opening. The open end of the liner may be glued to the lip of the canister opening and the liner charged with product before attaching a valve cup over the canister opening. Propellant may be introduced through a charging port at the base of the canister and the charging port sealed.
- This invention seeks to avoid some of the drawbacks of known barrier package aerosol dispensers.
- A barrier package for an aerosol container may have a body with a pleated plastic side wall which is strengthened as a result of formation of the side wall by re-heating, stretching and blow molding a pre-form. In fabricating a barrier package into an aerosol container, the package with attached valve cup may be positioned in the mouth of a canister so as to leave the mouth open and propellant injected into the mouth. An aerosol container may have a barrier package with a self-supporting pleated plastic body.
- In accordance with this invention, there is provided a barrier package for an aerosol container, comprising: a neck; a longitudinally extending body extending from said neck, said body defining a cavity open only at said neck; said body having a side wall, said side wall having a plurality of longitudinally extending pleats; said body being fabricated of a plastic such that said body is self-supporting; said side wall having an increased strength resulting from formation of said side wall by re-heating, stretching, and blow molding a pre-form.
- In accordance with another aspect of the present invention, there is provided an aerosol dispenser comprising: a canister having a mouth opening; a barrier package having: a neck; a longitudinally extending body depending from said neck, said body defining a cavity open only at said neck; said body having a side wall, said side wall having a plurality of longitudinally extending pleats; said body being fabricated of a plastic such that said body is self-supporting; pressurised gaseous propellant between said canister and said barrier package.
- In accordance with a further aspect of the present invention, there is provided a method of fabricating a barrier package aerosol dispenser comprising: press fitting a valve cup into an opening of a neck of a longitudinally extended self-supporting plastic barrier package having longitudinally extending pleats so that said valve cup is attached to said package; positioning said valve cup with attached package with respect to a canister having a mouth such that said package extends into said mouth but said mouth remains open; charging said canister with propellant through said mouth around said barrier package; seating a lip of said neck of said barrier package on an edge of said mouth and joining said valve cup to said edge of said mouth.
- In the figures which illustrate an example embodiment of the invention,
-
FIG. 1 is a partially cut away front view of a charged aerosol dispenser made in accordance with an embodiment of this invention, -
FIG. 2 is an exploded front view of the components of the aerosol dispenser ofFIG. 1 , -
FIG. 3 is a perspective view of a barrier package made in accordance with an embodiment of this invention, -
FIG. 4 is a front view of the barrier package ofFIG. 3 , -
FIG. 5 is a cross-sectional view along the lines A-A ofFIG. 4 , -
FIG. 6 is a perspective view of a pre-form for use in forming the barrier package ofFIG. 3 , and -
FIG. 7 is a cross-sectional view of the pre-form ofFIG. 6 . - Turning to
FIGS. 1 and 2 , anaerosol dispenser 10 has acanister 20 with acrown 26 having anopen mouth 28 bounded by afiller ring 24 formed by an annular, outwardly curled lip. Avalve cup 30 has a mating peripheral outwardcurled lip 34 so that the cup may be crimped to thefiller ring 24 in order to closeopen mouth 28. Cup 30 incorporates avalve mechanism 36. Thebase 38 of the valve cup has a reduced diameter. - A
barrier package 40 is contained incanister 20. It has aneck 42 also formed with an annularcurled lip 44 which, when the aerosol dispenser is assembled, is compressed between thefiller ring 24 and thecurled lip 34 of thecup 30. Thebarrier package 40 serves to separate the usable contents or product, which is not illustrated but which is contained within thepackage 40, from thepropellant 50 which is confined between the walls of thepackage 40 and the walls of thecanister 20. - The valve mechanism of
valve cup 30 has avalve stem 37 which extends inside the barrier package to proximate the convexbasal tip 48 of the package. - When product is injected into the
barrier package 40, it may expand from its original undeformed size illustrated bypackage 40 a ofFIG. 2 to an expanded filled size, illustrated by thebarrier package 40 ofFIG. 1 . - Turning to FIGS. 3 to 5, it will be seen that
barrier package 40 a is one continuous piece with anelongate body 46 depending fromneck 42.Body 46 has a plurality of longitudinally directedpleats 48 extending about its circumference.Package 40 a is made of a plastic material, such as a polymer plastic, such that the package is self-supporting but has some flexibility. For example,package 40 a may be made of Poly Ethylene Terephthalate (PET) or Polypropylene. The diameter proximate theconvex tip 48 ofbody 46 is preferably no greater than that ofopen mouth 28 ofcanister 20 so that thepackage 40 a may be readily inserted intocanister 20. The wall ofbody 46 may have a thickness of about 0.3 mm; the wall of the neck may be thicker, about 1.5 mm, such that the neck is significantly more rigid than the body, but flexible enough to allow for proper assembly without cracking. -
Barrier package 40 a may be formed by re-heating, stretching and blow molding a pre-form, such as the pre-form shown inFIGS. 6 and 7 . Turning to these figures, pre-form 70 has aneck 42 which is the same as (i.e., is indistinguishable from) theneck 42 ofpackage 40 a. However, thebody 76 of the pre-form, which depends fromneck 42, is substantially cylindrical and terminates in a convexbasal tip 78. The wall of thebody 76 and neck of the pre-form may have a thickness of about 1.5 mm. - To form
package 40 a from the pre-form, the sides of the pre-form are first heated so that they become ductile. Then the pre-form may be introduced into a mold having relatively cold walls defining a mold cavity that is shaped as the negative of thebody 46 ofpackage 40 a. A rod may then be inserted into the pre-form and pressed against itsbasal tip 78 to stretch thebody 76. This has the effect of orienting the plastic material at a molecular level, thereby strengthening the plastic material. Next pressurised air may be injected into the pre-form so that its side walls expand into contact with the cavity walls of the mold and freeze. Theresultant package 40 a may then be dropped from the mold. - To assemble and charge the
aerosol dispenser 10, thebarrier package 40 a may be first inserted into thecanister 20 until thelip 44 of itsneck 42 abuts thefilling ring 24. Next, thesmaller diameter base 38 of the valve cup may be pressed into theneck 42 of thebarrier package 40 a. The relative diameters of the base of thecup 30 and the opening in the neck of thebarrier package 40 a are such that this is an interference fit, which results in the neck stretching as it receives thebase 38 of thecup 30. This also results in joining the valve cup and barrier package in a sufficiently robust manner to allow further assembly. Next a vacuum may be drawn in thebarrier package 40 a through thevalve stem 37 of thevalve assembly 36 and thevalve cup 30, with attached barrier package, lifted a short distance off thefilling ring 24. This allows injection of propellant into the canister around the exterior of the barrier package through themouth 28 of the canister. The valve cup, with attached barrier package, is then again seated on thefill ring 24. Thelip 34 of the cup may then be crimped to the fill ring, sandwiching thelip 44 of the package between thefill ring 24 and thelip 34 of the cup. - Next product may be injected into the barrier package through the
valve stem 37. This causes the wall of the body of the package to expand and such expansion may continue until the wall of the body abuts the side wall of thecanister 20. The pleats of the body facilitate expansion of the package. Additionally, because the package is made of plastic, the walls of the body thin as the body expands. Indeed, the expanded package 40 (FIG. 1 ) may have a wall thickness of about 0.15 mm to 0.2 mm. - As product is dispensed through the
valve mechanism 36, thepackage 40 will contract from the pressure exerted by the propellant. The pleats assist in allowing the package to collapse in a predictable fashion as product is dispensed. Specifically, because thepackage 40 is made of a self-supporting plastic material, the pleats act as longitudinal reinforcing ribs. Consequently, the pleats resist longitudinal contraction of the package. On the other hand, the pleats more freely permit radial collapse of the package. Therefore, as product is dispensed, the package generally radially contracts to a point where opposite walls of the body may touch. And even at this point, the longitudinal pleats provide channels communicating the length of the package. Thus, the pleats resist the possibility of the package collapsing in any way which traps product in the package. - While the
canister 20 has been shown as having a cylindrical side wall, the canister side wall could also have a non-cylindrical shape. In such case, when the package is charged with product, the package would generally assume this non-cylindrical shape as the package expanded to contact the canister side wall. - Any pressurised gas may be used as a propellant, such as air, nitrogen, a hydrocarbon, or a hydrofluoroalcan. And the product may be any product for which it is desired to separate the product from the propellant. However, of course, neither the propellant nor the product should be caustic to the material of which the
package 40 is fabricated. -
Package 40 facilitates recycling of the aerosol container since the package may be burned off in a recycling process thereby avoiding the expensive, and therefore generally infeasible, task of separating thepackage 40 from thecanister 20. - Modifications will be apparent to those skilled in the art and, therefore, the invention is defined in the claims.
